Deep inelastic electron scattering on nuclei within a fully relativistic model

In a recent paper we have developed a theoretical frame suitable to handle finite systems in a fully covariant way preserving translational invariance. Further, we have also introduced the relativistic counterpart of the shell model displaying the same invariance properties. We apply now the above theory to a practical case, by investigating how a covariant single-particle description of a nucleus can be implemented on 4He , 12C and 16O and how the inelastic electron scattering, within the frame of the Plane-Wave Impulse Approximation (PWIA), can be recovered, still preserving the Poincaré invariance
